The second iteration of the practice tool design includes various components of the first iteration along with a new leaderboard design. This horizontal leaderboard shows the progress made by a learner as they earn points by answering questions correctly. An expanded version of the leaderboard also shows progress made for each community.

Another important feature added here is the 'View Node Tree' button. Whenever a question is answered incorrectly, the view node tree button opens a preview of the relevant question node and provides an explanation for the correct answer.
